Find the center and radius of the circle whose equation is given below: (x-1/2)2+(y-6)2=5
9514 1404 393
Answer:
center: (1/2, 6)
radius: √5
Step-by-step explanation:
The standard form equation for a circle of radius r and center (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
When we compare this to the given equation:
(x -1/2)^2 +(y -6)^2 = 5
we see that h=1/2, k=6, and r^2=5.
The center is (h, k) = (1/2, 6); the radius is √5.
Find the area of the shaded religion.
Giving brainliest! <3
Answer: 240 feet
Step-by-step explanation:
What you could do is find the area of the whole thing. 12x25 is 300. Then, you can find the area of the white part, which is 60, because you multiply 12x5. then, you would subtract 60 to 300, which would get you to 240 feet.
Answer:
The answer is : 240cm² for the shaded part
The unshaded part is = 60cm²
The whole rectangle = 300cm²
Step-by-step explanation:
Area is = WL
W = width (while the) L= length
The Area = 25 × 12 = 300
The area of the full rectangle is = 300
The unshaded part is = 5 × 12 = 60
So the shaded part is = 300 - 60 = 240cm²
[tex]so \: the \: answer \: is \: = 240cm^{2} [/tex]

What is factor?
A factor of polynomial P(x) is any polynomial which divides evenly into P(x).
How to find the solution for a polynomial?For finding the factor of a polynomial we will perform following steps:
If f(x) is any polynomial then substitute f(x) = 0.Then factorize the given polynomial by splitting the middle term. Then solve for x.According to the given question.
We have a cubic polynomial [tex]x^{3} -4x^{2} +ax -2a[/tex]
Also, x - 3a is a factor of the given polynomial.
⇒ [tex]x - 3 = 0[/tex]
⇒[tex]x = 3[/tex]
⇒ 3 is the one solution of the given cubic polynomial.
If 3 is the one solution of the cubic polynomial then it must satisfy the equation (i).
So, substitute the value of x in the given polynomial.
[tex](3)^{3} -4(3)^{2} + a (3) - 2a = 0[/tex]
⇒[tex]27 -4(3)^{2} +a(3) -2a=0[/tex]
⇒[tex]27 - 36 + 3a - 2a= 0[/tex]
⇒[tex]-9 + a = 0[/tex]
⇒ [tex]a = 9[/tex]
Therefore, the value of a is 9.

A random sample of 432 voters revealed that 100 are in favor of a certain bond issue. A 95 percent confidence interval for the proportion of the population of voters who are in favor of the bond issue is A 100 + 1.96 0.5(0.5) 432 100 + 1.645 0.5(0.5) 432 100 + 1.96 0.231(0.769) 432 0.231 +1.96 0.231(0.769) 432 0.231(0.709) 0.231 +1.6451 432
Answer:
The 95% confidence interval is [tex]0.231 \pm 1.96\sqrt{\frac{0.231*0.769}{432}}[/tex]
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
A random sample of 432 voters revealed that 100 are in favor of a certain bond issue.
This means that [tex]n = 432, \pi = \frac{100}{432} = 0.231[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
Confidence interval:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.231 \pm 1.96\sqrt{\frac{0.231*0.769}{432}}[/tex]
The 95% confidence interval is [tex]0.231 \pm 1.96\sqrt{\frac{0.231*0.769}{432}}[/tex]
Ignore the rotation 90 clockwise
Answer:
A reflection about y=x
Step-by-step explanation:
The 4 transformations are
TranslationRotationReflectionDilationLet eliminate which ones won't work.
A translation wouldn't flip the triangle in a different direction after translating it so we won't translate it.
A dilation changes the length for the triangle but the triangles are congruent so we won't dilate it.
A rotation about the orgin wouldn't work nor a specific point so a rotation isnt going to work.
A reflection will work so what will we reflect about.
Some corresponding coordinates are5,6 and 7,61,6 and 7,23,8 and 9,4.A reflection makes a reflected point equidistant from the line of reflection and their original point is equidistant from line of reflection.
So let find the midpoint of all the points and find a line where all of them are on.
The midpoint respectively are
6,64,46,6Let find the line that includes both these points.
[tex] \frac{6 - 4}{6 - 4} = \frac{2}{2} = 1[/tex]
So this means our slope is x. The y value corresponds with the x value so the answer is
[tex]y = x[/tex]
So the answer is
"A reflection about y=x

The RAND() function in Excel returns a pseudo-random number between 0 and 1. If you enter this function into 1000 cells (i.e. enter the formula in one cell and copy it to 999 other cells), approximately how many of these cells will contain values less than or equal to 0.2?
a. A number relatively close to 1.
b. A number relatively close to 10.
c. A number relatively close to 100.
d. A number relatively close to 500.
e. A number relatively close to 1000.
Answer:
c. A number relatively close to 100.
Step-by-step explanation:
Given
[tex]Range: 0 \to 1[/tex]
[tex]N =1000[/tex] --- i.e. the cells
Required
Number of cells that contains less than or equal 0.2
Less than or equal 0.2 means that the numbers are approximately 20% of the whole distribution
So, to calculate the number (n) of these cells, we do the following computation
[tex]n = 20\% * N[/tex]
[tex]n = 20\% * 1000[/tex]
[tex]n = 200[/tex]
200 is closer to 100 than 500. Hence, (c) is correct

Hope this helps!
Good Luck!
Please mark me bralinest if you can :)
Answer:
Vertical
Step-by-step explanation:
<AGB and <EGD are vertical angles because they are vertically opposite from each other since they were created from two lines crossing.
-You know that they aren't adjacent because they aren't next to each other and don't share a side or a vertex.
-They can't be supplementary because they don't add up to 180 degrees
-They can't be complementary because they don't make up 90 degrees

Una función se define como un conjunto de parejas ordenadas (x, y) donde no se repite el valor de "x" (corresponde al dominio de la función) En el caso específico del ejercicio, la alternativa C no corresponde con una función ya que tienen dos parejas con el mismo valor de "x": {(-2,1), (-1,0), (0,1), (-1,2), (2,2)} Estos pares están en negrita, y el valor repetido subrayado.
